Like a fire extinguisher in your house or an earthquake kit, it's always better to be prepared. Although rare, diesel engine runaway is caused when external hydrocarbons are drawn into the engine and can cause overspeeding and catastrophic engine failure. Life, limb, and your vehicle are put in jeopardy. BD Diesel Performance has you covered should the worst happen with our Electronic Positive Air Shutdown (E-PAS) units by cutting the intake air supply to the cylinders and safely shutting down the engine. The E-PAS controls the electronic throttle body in the intake manifold found on most late-model diesel engines by closing it to shut off the air supply in emergency situations. The E-PAS can be easily installed in less than 1.5 hours with factory plug-in connectors and premade wiring harnesses. Automatically resets itself after shutdown and can be easily removed for truck lease returns.
